Answer:
11°F = (-23.88°C ) = (249.12K)
Explanation:
Use this formula to convert °F to °C
[tex] \degree \: F \: = \frac{9}{5} \degree \: c + 32[/tex]
Now make C as the Subject
[tex]f - 32 = \frac{9}{5} c \\ \frac{5(f - 32)}{9} = c[/tex]
Now put the °F value and solve
[tex] \frac{5(f - 32)}{9} = c \\ \frac{5( - 11- 32)}{9} = c \\ \frac{5( - 43)}{9} = \degree \: c \\ \frac{ -21 5}{ 9 } = \degree \: c \\ - 23.88 = \degree \: c[/tex]
So,
[tex] - 11 \degree \: f = - 23.88 \degree \: c[/tex]
To do that you have to add 273 to the Celsius
[tex] - 23.88 + 273 =249.12 k \\ [/tex]
